Objective: This study evaluated the effects of dexmethylphenidate on problem behavior during functional analyses conducted across dexmethylphenidate and placebo conditions for a child with multiple disabilities.

Methods: We conducted functional analyses in a multielement format embedded in a withdrawal design and collected data on the frequency of disruptive behavior and duration of crying.

Results: Results suggest disruptive behaviour was maintained by attention when DMPH was absent, but not when it was present. Results also suggest DMPH may have had collateral effects on the probability of non-targeted behaviour (crying). Consistent with previous research, functional analyses exhibited a change in disruptive behaviour’s function between medication and placebo conditions.

Conclusion: These findings provide further support that stimulant medication may change the function of disruptive behavior and highlight the need to investigate the effects of stimulants on non-targeted behaviors.

目的：本研究评估了右旋多哌啶对安慰剂患者的功能分析过程中右旋哌醋甲酯对问题行为的影响。

方法：我们以撤消设计中嵌入的多元素格式进行了功能分析，并收集了有关破坏行为频率和哭泣持续时间的数据。

结果：结果表明，当缺乏DMPH时，注意力会保持破坏性行为，而在没有DMPH时则不会。结果还表明，DMPH可能对非针对性行为（哭泣）的可能性产生了附带影响。与以前的研究一致，功能分析显示药物和安慰剂条件之间的破坏性行为功能发生了变化。

结论：这些发现为刺激药物可能改变破坏性行为的功能提供了进一步的支持，并强调需要研究刺激剂对非靶向行为的影响。
